What is the function of BIOS on a SCSI adapter?
SCSI adapter BIOS, when enabled on a PC, allows boot access from a SCSI attached drive, rather than an integral IDE disk. This means the SCSI drive can be seen by FORMAT as a C: drive for the OS (using a Windows metaphor).
The BIOS (basic input/output system) is needed during boot so the "hardware" knows where to go when looking to load an operating system. After the boot block is read off the disks and initial drivers are loaded, the BIOS hands over control to the operating system to continue with the boot process.
